Summary

One of several objectives in a swine feeding program is to make optimum use of the protein in the diet. The balance of amino acids in the ration will be use d more for maximum gains and efficiency of feed utilization. The percent crude protein in the ration can be less than present standards, provided the amino acid supply is adequate and present in the proper ratio . On the other hand, meat type animals require adequate protein for muscle development, which increases the need for more protein in the ration. Because the competition for protein feed will be come greater in the future and because the amino acid requirement of the meat type pig is not well defined, more information is needed on feeding amino acids to modern pigs. Lysine is one of the more limiting amino acids in swine rations, although it is considered adequate in most corn-soy type rations by most nutritionists. When lysine has been added to the ration, the results have not shown a consistent benefit with lysine. In the earlier research at this station there have been good responses with some treatments of lysine in the water, but other times the response has been negligible. One of our objectives is the understanding of the difference in the effects we have observed and to develop a consistent response with lysine. The objective of this trial was to determine the effect of adding different levels of L-lysine hydrochloride in the drinking water when the pigs were fed a corn-soy ration which was lower in protein content than normally recommended at the respective weight of the pigs.
